That's funny. Obviously cities go back thousands of years, but I don't think it was the norm for the majority of humans to live in them until the last several hundred years or less. But in general, I do believe humans have fewer group social activities than we used to, and therefore fewer opportunities to meet new people.

There's a cultural aspect to this too. I know in China it's common for parents to be matchmakers and find other parents that have single kids for them to go on dates with. And historically in India arranged marriage has been common. So I'm probably looking at this from a western lens. But still, as far as dating goes online dating seems to be the modern evolution of it. And in my opinion an improvement.
